BALL-COCK.

Specification of Letters Patent.

Patented Jan. 19, 1909.

Application le. June 11, 1907. Serial No. 378,364.

T 0 all whom it may concern:

Be it known that I, FRED CLARK, a citizen of the United States, and aresident of the city oi" New York, New Brighton, borough of Richmond, inthe county of Richmond and State of New York, have invented a new andImproved Ball-Cock, of which the 'following' is a full, clear, and exactdescription.

This invention relates to ball cocks such as are used in connection withflush tanks.

The object of the invention is to provide a construction which willenable the valve or cock to operate effectively and substantiallynoselessly.

The invention consists in the construction and combination of parts tobe more fully described hereinafter and particularly set forth in theclaims.

Reference is to be had to the accompanying drawings forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in the ligure.

The figure is a vertical section through a flush tank and a ball cockconstructed according to my invention, certain parts being shown inelevation.

Referring more particularly to the parts, 1 represents a tank, which isof the usual construction. On the upper edge of this tank the body 2 ofthe ball cock is mounted. This body 2 comprises a vertically disposedbarrel 8 having a horizontal tubular neck 4 to which a supply pipe 5 isattached as indicated. The lower end of the barrel 3 is closed by athreaded removable plug 6 in which there is mounted a drip tube 7, thesaid tube being rigid in the plug, as will be readily understood. Thistube extends upwardly within the interior of the barrel 3 to a pointnear the upper end thereof, and its upper extremity constitutes a seatfor a valve or disk S. This disk is provided on its under side with awasher or packing disk 9, and these parts are held between nuts 1() onthe threaded extremity of a valve stem 11 which passes upwardly throughthe drip tube 7 as indicated. In this connection it should be observedthat the lower end of the drip tube is open and disposed near the bottomof the tank. The lower end of the valve stem 11 is threaded so as toaord means for attaching an adjustable cross head 12, said cross headbeing provided with a set screw 13 which enables it to be readilyattached to the stem 11 in any adjusted position desired.

Near the lower end o1 the tube 7 a guide plate 14- is rigidly attached,and this plate is provided with an opening 15 through which a valve rodor valve-operating rod 1G is adapted to slide. This valve rod isoperated by means of a float or ball 17, and for this purpose the lowerend of the barrel 3 is 'formed into a laterally projecting bracket 18,which bracket is formed into an upwardly projecting bifurcatcd post 19.In the upper part of this post a lever 20 is mounted upon a pivot pin21, and the short arm of this lever is pivotally attached by a pin 22 tothe upper end of the valve rod 1G, said valve rod being guided through aguide opening 23 formed in the bracket as shown. The float or ball 17 iscarried upon an arm 24- having a head Q5 which is pivotally attached ona pin Q6 in the lower part 'of the post 19. The head 25 is connected bya link 27 with the aforesaid lever 20. From this arrangement it shouldbe understood that erates to hold the valve 8 upon its seat, so r thatthe valve is closed and the supply ot' water to the tank is cut off.

The valve disk 8 is guided in a removable cap 28 which has a threadedconnection with the upper end of the barrel 3 as shown. When it isnecessary to renew the packing disk 9, it is onlynecessary to removethis cap, whereupon the parts are within easy reach. In this connectionit will be observed that the upper end of the drip tube 7 lies quitenear the upper end of the barrel 3, so that when the cap 28 is removed,these parts are exposed.

The arrangement for connecting the valve rod 16 with the valve stem 11,enables the parts to be readily adjusted so that the valve will seat atany desired position of the ball or float 17.

It should be understood that the ball cock operates in the usual manner;that is, it is opened wide by the full descent of the float 17, andcloses gradually as the float rises with the level of the water in thetank. As the tube 7 has no opening to the tank except at its lower end,it follows that when the water flows into the valve it must enter thetank through the drip tube 7, the mouth of which is below the low waterlevel in the tank, so that there is substantially no noise from thefalling water, and no splashing of water from the tank can occur.

Attention is called to the fact that the tube 7 is imperforatethroughout its length, and hence there is no opportunity for water todrip through and fall to the interior of the tank outside of the tube.1With my arrangement, the valve is attached at the upper edge of thetank in the usual way, while the water introduces itself to the tank ator near the bottom.

Having thus described my invention, l claim as new and desire to secureby Letters Patent:

l. in a ball cock, in combination, a tank, a valve, a valve body, a tubeextending downf wardly from said body to a point near the bottom of saidtank, a float, a stem extending downwardly in said tube to a point nearthe lower end thereof, and a valve operating rod connected with saidfloat, extending` down at the side of said tube and attached to saidstem.

2. ln a ball cock in combination, a valve body, a plug mounted in thelower side thereof, a tube fixed in said plug and eX- tending upwardlyinto said body, a valve disk seating' on the upper end ot said tube, aremovable cap on the upper side of said body, a stem attached to saiddisk and passing downwardly within said tube, a valveoperating rodextending downwardly substantially vertically and connected with saidvalve stem below said tube, and a float atbody, a tube attached in saidplug, eXtending upwardly within said body and extending downwardly to alow level, a disk seating on the upper end oit said tube, a valve stempassing downwardly through said tube and attached to said disk, saidstem pro-Y jecting from the lower end of said tube, a

valve operating rod extending` downwardly at the side of said tube, aconnection between said stem and rod, and a oatconnected with said valveoperating rod.

4L.. In a ball cock, in combination, a tank,

a valve body, the axis whereof is disposed in a substantially verticalposition, a removable plug having` a thread connection in the lower endof said body, a drip tube passing ulowardly through said plug from belowforming a valve seat at. its upper end, and extending downwardly belowthe normal water level in said tank, a valve seating on the upper end ofsaid drip tube, a iioat, a valve stem connecting with said valve andextending downwardly in said tube, and a valve operating rod extendingdown at the side ot said tube and attached to said stem.

ln testimony whereof l have signed my naine to this speciication in thepresence of two subscribing witnesses.
